Google Doesn't Forget, They Have Lots Of Storage

Google's John Mueller responded on Twitter about if Google forgets about links over time, in which he responded "we have a lot of storage." That, to me, clearly means no. Google has said in the past that Google algorithms don't forget - here is John Mueller telling that to a webmaster yet another way.

Does Google forget about your old spammy links? Nope - they store that for a long long time according to this tweet.

But of course, even if Google might not forget, they still may forgive - right? At least that has been Google's message with Penguin going real-time, disavow links tool, nofollow attribute, reconsideration requests and more.
